'This invention relates to a transfer machine and more particularly to amachine for posting ledger sheets by the process of preparing a negativerecord on the back of the original record and through the use of asuitable solvent and pressure transferring the negative record to theface of the ledger sheet.

Such transfer machines in the past have accomplished the transfer of thenegative record or. carbonfrorn the back of the original record bysqueezing the solvent from a ribbon through the original record so thatthe subsequent ressure transfers the then wet carbon impression to theledger sheet. The original is .then moved forward United States Patent 0to the next position as theledger sheet and ribbon remain in a standbyposition. In accordance with the present invention an improved machinehas been devised which utilizes a container of solvent fluid underpressure and a tubing for carrying the solvent, said tubinghaving aseries of drilled jets so that the solvent may be released as a spray.Control means are provided to release the solvent" spray ju'st prior tothe' moving forward of the original sheet to the print position. and thespray is applied directly to the carbon side of the original sheet.

The use of such a pray system results in many advantages particiilarlyfrom the standpoint of greater speed 7 of operation and better printingquality.

Accordingly, the main objectof the present invention is to provide atransfer machine having an improved moistening' device" for the recordsheets employed in such machine.

A further object of the present invention is to provide atransfermachine having moistening means for applying solvent directlyonithe carbon side of the original sheetto obtain better printingquality. v

A further" object of the present invention is to provide a transfermachine provided with means for. spraying the s'olventon'jthe carbonside ofthe-original sheet before the original sheet is shifted intophysical contact with the ledger sheet thereby greatly, speeding uptheposting operation. v I g Y A-, still further objectof the presentinvention isto provide, a transfer machine having a moistening devicewhich permits :the. use at a nomtoxic solvent which can be less se'verein its action since it is not required to force the solvent through thepaper to release particles of ,Afurther object of the present inventionis to provide an improved transfer machine wherein space is saved bytheelimination of miscellaneous parts such as a solvent pan,ink'ribbomribbon feed mechanism, and the like.

other objects of the invention will be pointed out in I the followingdescription and claims and illustrated in FIG. 2V is a detail view ofthe posting mechanism and the sheet feeding devices. H I

view of the clutch and clutch release 3,007,402 Patented Nov. 7, 1961The original paper from which the copy is to be taken is printed in aconventional manner on a tabulator, typewriter or other suitable mediumand is backed with suitable carbon paper while being printed. Theoriginal .may take the form of single sheets, fanfold or continuousroll.

. The machine in its general operation is substantially the same as thatdisclosed in Patent No. 2,282,737, granted. May 12, 1942. The generaloperation will, therefore, be but briefly described with theimprovements of the present invention more particularly explained. v

The machine includes a table or plate 2 1 (FIG. 2.) supported betweenside frames 22 and 23" (FIG. 3). Upon this table is placedthe ledgersheet'to receive the impression. The frames 22 and 23 are rigidly joinedby a lower pressure bar 24, bar 25 and a motor support plate 27. AinotorZS -(FI-G. 3) provided to drive the several mechanisms ofthe'machine is mounted on the plate 27. The motor, through a pulley andbelt connection 29 and a gear box 30 supported on the plate 27 operatesa short shaft 31 supported in bracket 32 and securedto'the plate 27. Aclutch disk 34 (see also FIG. 4) fast on the shaft 31 isprovided withnotches 35 about its periphery,

with which notches a clutch pawl 36 pivotally carried by p a clutch arm37 fast on a cam shaft 38 cooperates. The

' cam shaft 38 is supported in brackets 39 secured to the plate 27, theshaft 31 and 38 being in axial alignment. The arm 37 a (FIG. 4) andshaft38 are normally held against rotation by an arm 40 fast on a stud 41supported by the bracket 32. The arm 40 has a shoulder 42 which normallylies in the path of the arm 37 and of a tail of the pawl 36, thusholding the pawl 36 out of engagement with the disk 34. A stud 43 on thearm 40 fast on the stud 41 projectsthrough a slot 45 in a'link !46 whoseright-hand end is supported by a spring 46a. The other end of the linkis connected to an arm 47 fast on a shaft. 48 jo-urnaled in the frames22 and 23. Also fasten the shaft 48 is a release bar 49, located nearthe end of the shaft and being arranged to lie conveniently I on oneside of the table 21. v i i Inorder to initiate an operation ofthe.machine, the

operator depresses the bar 49,, which movement rocks the shaft 48 andarm 47 counterclockwise thrusting the link 46 toward the right. At thismovement, the left edge of notch 45 engaging the stud 43 rocks the armthere- 56. The arm 37 and the shaft 38 make one .with,- removing theshoulder 42 from engagement with the arm 37 andthe tail of the-pawl 36.The pawl thus freed, is engagedwith one of the notches 35 by-a springcomplete counterclockwise rotation. 1 I a A cam 57 fast on the shaft 38adjacent the extension 50 of link 56 has a single notch in its peripherycooperating with "a roller 58 on the extension 50. As soon as the shaft38 starts to rotate, the cam 57 rocks the exten-' sion 50 clockwisefreeing the arm 40 to be acted upon by a spring 59 which immediatelyrestores the arm to itsnormal position. Near the end of the rotation ofshaft 38, the shoulder 42 reengages and rocks the, pawl 36 out ofengagement with the disk 34 and stops the arm 37 and shaft 38. A springpressed retaining pawl '60 prevents retrograde movement or rebound ofthe arm 37.

If the operator has released the bar 49 before the'end of therotation'of shaft 38, the parts assume their normal other operation maybe initiated.

' positions when the notch in cam 57 comes opposite the spring '61having one end attached to an arm 62 fast on tached to a gripping shield51a slidably mounted on a rod 52 supported for oscillation between theframes 22 and 23. The ledger sheet 63 is placed in position on the table21 and manually shifted to position beneath the pressure bar 83, atwhich pointit is directly under the fingers 51. The fingers are nowadjusted along the rod 52 to bring the fingers in line withthe limitsbetween wihch is it dethe shaft 48 to restore the link toward the leftbefore an- Ledger carriage The ledger sheet indicated at 63 (FIG. 2) onwhich the transfer is to be made is placed on the table 21, with thefirst line (in the case of a new sheet) or the next blank line on whicha copy is to be made beneath a transparent line finder 64 adjustablymounted on a bar 55. This finder V has parallel lines scribed thereon toassist the operator in the proper positioning of the ledger sheet. Thesheet is located on the table 21 with its left edge beneath springpressed clamps 65 (FIG. there being four clamps 65 mounted on the ledgercarriage.

The ledger carriage includes a bar 66 (FIG. 5) integral with a pair ofspaced blocks 67 slidably mounted on rods 68 which are supported inbrackets 69 (FIG. 3) secured to and extending inwardly from the leftside frame 22. The clamps 65 are slidable vertically in the bar 66 andare normally urged downwardly to grip the paper 63 by blade springs 71secured to the under side of the bar 66.

After the ledger sheet is in proper position, the operator depresses therelease bar 49 whereupon the shaft 38 rotates. Shortly thereafter, a cam72 (FIG. 5) permits a spring 73 to rock clockwise an arm 74 mounted on ashaft 75 supported in the brackets 39 (FIG. 3). An arm 76 fast to ashaft 77 (FIGS. 3 and 5) is connected by a link a 78 to the arm 74. Alsofast on the shaft 77 is a bell crank 79 whose downwardly extending armis connected by a link 80 to a bell crank 81 pivoted on a studprojecting from a fixed bracket. A bar 82 supported on the bell cranks79 and 81 is normally pressed upwardly against the paper clamps 65 andagainst the tension of springs 71 by the cam 72.

The clockwise movement of the arm 74 described above is transmitted bythe link 78 to rock the arm 76, shaft 77,

bell crank 79 and due to the connection 80 the bell crank 81counterclockwise to lower the bar 82. This permits the springs 71 todraw the clamps 65 down gripping the ledger sheet firmly between saidclamps and the carriage bar 66.

Shortly after the ledger sheet'is gripped in the manner just described,mechanism now to be described is operated to shift the carriage adistance sufiicient to move the selected line from its position beneaththe line finder (FIG.

" 2) to a position under a pressure bar 83. This mechanism includes apair of earns 84 (FIGS. 3 and 6) cooperating with a bell crank 85pivoted on the shaft 75 and i which is connected by a link 86 to an arm87 fast to a shaft 88 supported between the side frames 22 and 23. An-

other arm 89 also fast on the shaft 88 carries at its free end a pin 92extending between spring connected arms'91 spring 97.

As the shaft 38 rotates, the bell crank 85 is rocked clockwise, whichmovement through the link 86 rocks the arm 87, shaft 88 and arm 89 inthe same direction. This movement through the link 96 draws the carriagetoward the right (FIGS. 2 and6) and toward the rear of the machine forthe purpose set forth above.

In order to align the typed matter on the original sheet with the propercolumn on the ledger sheet, there is provided a plurality of indexfingers 51 (FIG. 2) each atsired to have the transfer appear. With thefingers 51 in their selected positions, the original sheeet'153 isinserted and the first line of typed matter is positioned with the topof the typed matter aligned with the bottoms of the fingers 51. The arms164 (FIG. 2) are now operated to bring the rolls 139 into contact withthe roll 137, thus holding the original sheet 153 in position.

M oistening device As was previously mentioned, the moistening deviceemployed by prior transfer machines, such as disclosed in the patentreferred to, comprised a solvent reservoir and a ribbon for applying thesolvent to the non-carbon side of the original sheet. In accordance withthe present in- "vention this type of moistening device has beenreplaced with an improved arrangement which' utilizes a container ofsolvent fluid under pressure and a tubing for carrying the solvent. Thetubing has aseries of drilled jets so that the solvent may be releasedas a spray just prior to the moving forward of the original sheet to theprint position and the spray is applied directly to the carbon side ofthe original sheet.

Referring to FIGS. 1 and 2, the container C of solvent fluid underpressure preferably is of the pressure bomb type of which there are manyon the market which could be used. The container is mounted in anysuitable fashion and has an outlet tubing T1 for transmitting the fluidin the container into a control valve V. Leading out of the valve isanother tubing T2 which extends downwardly and then laterally across themachine. The laterally extending portion of tubing T2 is provided with aseries of small spray holes S (FIG. 1) and is located in a positionwhich is approximately one line space in advance of the pressure bar 83at the impression transfer position. As shown'in FIG. 2, the laterallyextending spray portion of tubing T2 closely underlies the master ororiginal sheet 153 and the solvent is sprayed directly on the mirrorimage appearing as a coated deposit on the back of the original sheet;

The transfer operation may be performed approximately three times fasterwith the present arrangement by reason of the fact that the solventmaterial is sprayed on the master sheet before the master sheet isshifted into physical contact with the copy paper and this improvementin time permits the use of a non-toxic solvent which, for example, mayconsist of only alcohol and Freon gas and which can be less severe inits action since it is not required to force the solvent through thepaper to release particles of carbon or ink.

The valve V controls the release of the solvent and may take anysuitable form. For example, as shown in FIG.

V on the end of the plunger.

8, a valve may be provided which comprises a spring tensioned slidableplunger P which normally obstructs the how of solvent between a port Aassociated'with tubing T1 and a port B associated with. the tubing T2.The plunger includes a through hole H and may be moved upward toposition the hole in alignment with the parts and thus release thesolvent for a spraying operation.

For cyclically operating the valve plunger there is provided a sector122 (FIG. 2) free on a shaft 114 and having a camming lobe L whichcoacts with a flange F A cam '115 on the shaft 38 rocks an arm 116 onthe shaft counterclockwise against the tension of a spring 133 and by aconnection 117 rocks a lever 118 clockwise. The lever 118 is secured ona shaft 112 whose one end has an arm 118a fast there- 121 on the sector122 rocking the sector counterclockwise against the. tension of a spring132 causing the camming lobe L to engage the plunger and open. the valveto release the solvent spray.

' Pressure bar The pressure bar .83 is slidable vertically in grooves125 in the side frames 22 and 23 (FIGS. 1 and 2) and is operated by apair of links 126, one being pivotally connected to the bar 83 near eachend. The links 126 are connected at their lower ends to arms 127 fast ona shaft 128 (FIG. 3), one of said arms being disposed near each end ofsaid shaft. Anarm 127a (FIG; 3) is connected by a link 129 to one arm ofa bell crank 130 pivoted on the shaft 75. A pair of cams 136 on theshaft 38cooperates with antifriction rollers on the bell crank- 130 torock it first clockwise and then counterclockwise-to normal. Theclockwise movement of'the follower through the link 129, arms 127 andlinks 126 lowers the pressure bar 8310 cause the transfer and thecounterclockwise movement of said bell crank 130, through the samelinkage, raises the pressure bar to normal position. I Y

' Paper feed original I Referring to FIG. 2, a feed roll '137 is mountedon a shaft 138 journaled in the frames 22 and 23. A plurality ofpressure rolls 139 each carried between a pair of arms 140 are pressedagainst the roll 137 by springs 141. The arms 140 are pivotally mountedon a shaft 142 supported in brackets secured to the cross bar 25.

Secured to one end of the shaft 138 is a ratchet wheel 144 (FIG. 7) withwhich cooperates a spring pressed feed pawl 145 carried on an arm 146free on the shaft 138. A link 147 connects the arm 146 to an arm 148pivotally supported on the frame 22. An antifriction roller 149 normallyrests on the flattened end of an arm 150 secured to the shaft 88.

It will be remembered that the shaft 88 rocks first clockwise and thenback to normal position under the influence of the cams 84, the arm 150making a similar excursion (FIG. 3). When the arm 150 rocks clockwisefrom beneath the roller 149, a spring 151 draws the arm 148 and link 147downwardly rocking the arm 146 clockwise to retract the pawl 145. Aftera transfer has been made, the cams 84 cause the arm 150 to rockcounterclockwise to normal position, at which movement an inclined orcam surface 150a of the arm 150 moves the link 147 upwardly rocking thearm 146 counterclockwise to feed the original copy one line space. Aspring pressed retainer 152 serves to hold the roll 137 and the originalcopy in alignment.

The original from which a transfer is to be made, indicated at 153 inFIG. 2, is inserted over a shield 154 passing between a bar 155 and aplate 156, between the feed roll 137 and the rolls 139 and over the arms'140. The bar 155 is carried between two arms 159 pivoted on a shaft 160supported in the brackets 143. The plate 156 is secured to the shaft 160and is normally held in the position in which it is shown in FIG. 2 bysprings 162 attached to levers 163 which are also secured on the shaft160.

In order to insert an original copy sheet, a pair of arms 164 (FIG. 2)is rocked counterclockwise. These arms are secured one on each end of ashaft 165 journaled in the brackets 143, and which shaft is providedwith notches into which fit the arms 140. Upon counterclockwise movementof the arms 164 and shaft 165 the flattened portions of the shaftbearing against the arms 140 rock these arms also counterclockwise toseparate the rollers 139 from the feed roll '137. During this movementstuds 166, one on each of the arms 140, contact the plate 156 and carrythe latter therewith, the parts being shown in their moved positions indotted outline in FIG. 2. This provides a free passage for the originalsheet 153 between the bar 155 and plate 156 and between the feed roll137 and the pressure rolls 139.

6 Whenflthe arms, 164 are restored clock-wise to their normal position,the springs 141 press the original sheet 153. tightly between the rolls139 and thefeed roll 137.

The clockwise movement of the bar 155.is limitedby the arms 159 strikingcollars on the shaft, 138 and with the parts intheirnormal position, asshown in FIG. 2, there is a slightclearance between the bar 155 andplate '156 topermit-free movementofthe original 153 when line spaced asabove described.

At the completion of atransfer operation and as soon as the pressure bar83starts moving upward to release the pressure, the mechanismillustratedin FIG. 6 moves the ledger carriage to its original position and the cam72 (FIGS) raises the bar 82 to release the grippers 65. The operator maynow adjust the ledger sheet 63 to the. next line or insert another sheetto the next unused line. Also vnearthe end ofthe-restoration oflthepressure bar, the paper feed mechanism .(FIG. 7 operates to feedtheoriginal sheet 153 one line space and cam 115 is timed to effect therelease of the spray solvent just prior, to this movement. t 1
